TO ADJUST SANDING BELT TRACKING
See Figure 10.
n
Connect the sander to power supply.
n
With sander positioned as shown below, pull switch trig-
ger and release immediately.
NOTE: This position is for adjustments only. Sanding belt
should not be in contact with workpiece or any foreign ob-
jects when making belt tracking adjustments.
n
Observe tracking of sanding belt. If the sanding belt runs
inward, slowly turn the tracking knob clockwise. If the
sanding belt runs outward, slowly turn the tracking knob
counterclockwise. This should be done until you are sure
belt will not run off sander, or come in contact with internal
parts.
NOTE: After installing a new sanding belt, it may become
necessary to change the adjustment several times until the
belt becomes conditioned.
CAUTION:
If the sanding belt wears excessively on the inner
edge it is probably adjusted too far inward and is
rubbing against internal parts. If this is the case,
readjust the tracking knob.

When you are sure the belt will not rub against internal
parts, start the sander and fine adjust the tracking knob
until the belt stabilizes.
When correctly adjusted, the outer edge of the belt will
be even with the outer edge of the sander. Belt life will be
greatly increased if a few seconds are spent adjusting the
belt tracking.
NOTE: Replace a torn sanding belt immediately.
WARNING:
Keep hands and fingers away from moving
sanding belt. Any part of body coming in contact
with moving sanding belt could result in serious
injury. Do not wear loose clothing or jewelry when
operating sander. They could get caught in moving
parts and foreign objects could get thrown from
sander causing injury.
